WlNlDDWPANE-FSTENING STEM-E.

Application tiled August 9, 1922. Serial No. 550,653.

To @ZZ whom it may concern.'

Be it known that I, JOHN R. GAMMETER, ,a citizen of the United States, residin at Akron, in the county of Summit and l tate of hio, have invented a certain new and 2e final surface-finishing operations are com-v paratively laborious and costly.

The object of my invention is to provide an improved pane-fastening strip having the desirable features of wood Without its objectionable properties, and to that end l have devised a strip made of a relativelylight, hardened, plastic material capable of taking a vgood finish, adapted to be softened by heat and to take a permanent set when 3o cold, capable of being sawed and worked like Wood, penetrable by nails or other pointed fasteners Without splitting, and adapted to be made of uniform texture and at a relatively-low cost;

Of the accompanying drawings, Fig. 1 is a perspective view showing part of the interior of an automobile body and illustrating two slightly-differing applications of my invention. e0 Fig. 2 is a sectional perspective view showing one form of my improved retaining strip with a part of the cover removed.

. Fig. 3 is a sect-ional perspective view showing another form. l

In the drawings, 10 is the rear window.- pane of an automobile, the frame of .this Window being of a type having all four corners rounded, and 11 is a side pane Whose frame has at least one rounded corner.

12 is a strip adapted to take the place of the. ordina-ry retaining strip for rear Windows. which is commonly made of rattan wood. The body 13 of this improved strip is composed of a hardened, thermo-plastic material having a cellular internal structure or core 14e and a dense external portion or skin 15 integral therewith. l( prefer to use sponge hardl rubber for the purpose, it being a material which canbe readily molded te any desired sha e, of uniform texture, and is relatively lig t and workable by sawing, etc., like wood, but is non-splitting when penetrated by nails or other pointed fasteners. 16 is a textile covering of any suit able character such as felt or asoft, napped Woven cloth, firmly attached by vulcanizing to the strip-body 13 to act as a cushion and packing against the pane.

17 is another form of the retaining strip applied to the side window-pane 11, being a so made of sponge hard rubber with a cellular core 14 and a dense outer surface 15, but in this case the textile covering is omitted. An angular groove 18 is molded along one corner edge to receive a suitable packing. This strip may be given a smooth surface in the mold and may in addition be polished by the usual methods employed in finishing hard rubber, or it may be painted and varnished. By using one or more pigmentspin the compound the rubber may be colored as desired and the colors'may be str'iated to give grained edects.

My im roved retainin strips can be used in straig it form or can e bent to a desired curvature at any selected locality on softening the material with a moderate degree of heat. The heat can be applied by placing the strip in an oven, or on a hot-plate or in hot Water or otherwise as may be found convenient.

These strips are particularly suited for window-pane retainers but may also be employed for any analogous purpose.

I claim:

1. A window-pane retaining strip com posed of a cellular, hardened, plastic material adapted to be softened by heatto permit the bending of the strip.

2. A window-pane retaining strip -composed ofa thermo-plastic, hardened material having a cellular internal structure and a dense outer surface.

3. A window-pane retaining strip composed of sponge hard rubber.

4. A window-pane retaining strip compoed of hard rubber having si, dense er@ termal Surface and a cellular internal structure.

5. A window-pane retaining strip com- 5 posed of cellular hard rubber and having e textile covering vulconizel thereon.

@.A window-peine reteiming strip commoete@ posed of herd rubber having a, dense external surface und e cellular internal structure, end textile covering vulcanized on said E@ externel surface. lin witness whereof l( have hereunto set my hond this 3 doy of Aust 1922.
